Somatic recombination in Schizophyllum commune.
A CONSIDERABLE effort has been put forth in the past few years to elucidate the mechanisms of internuclear genetic exchange in vegetative mycelia in the fungi (PONTECORVO 1956; RAPER 1959; DAY 1960a). PONTECORVO (1956) described a system whereby, following the formation of a heterokaryon and a diploid nucleus, the phenomenon of crossing-over was a process distinct from that of haploidization. C...
متن کاملFruiting Dikaryon of Schizophyllum commune
The patterns of polypeptides synthesized by two co-isogenic monokaryons and the derived dikaryon of the basidiomycete Schizophyflum commune, growing in surface culture, were compared by two-dimensional PAGE after labelling with [35S]sulphate. Synthesis of most of the polypeptides (400 analysed) was common but at day 3 some 30 polypeptides were synthesized in the dikaryon which were not seen in ...
متن کاملThe Genetics of Schizophyllum Commune.
URING the course of an investigation on sexuality and related phenomena Din the common wood-rotting mushroom, Schizophyllum commune, a continuing search has been maintained for appropriate genetic markers for use in the work. A wide variety of morphologically aberrant and biochemically deficient strains has accordingly been tested for single locus segregation and for possible linkage with the f...
متن کاملA common-AB diploid of Schizophyllum commune.
N Schizophyllum commune, a heterothallic basidiomycete, compatibility is con' trolled by two unlinked mating factors, A and B. Matings between two strains with dissimilar A and B factors (i.e. AI BI x A2 B2) result in the establishment of the dikaryon, tho secondary mycelium, which possesses two haploid nuclei per cell. The diploid phase, normally confined to the basidium borne on the dikarycm,...
متن کاملAllergic fungal sinusitis caused by Schizophyllum commune
A case of allergic fungal sinusitis (AFS) due to Schizophyllum commune was reported. The pathogen was identified using molecular bioanalysis. The patient underwent the functional endoscopic sinus surgery followed by the radical maxillary sinusotomy with canine fossa trephine. This case suggested that complete surgery allowed optimal disease clearance for AFS caused by Schizophyllum commune.
